To know the bacterial ecology of ENT infections and to evaluate the susceptibility to antibiotics of the offending germs at the hospital center of Marrakesh.
Patients and Methods:
This is a descriptive retrospective study between January 2017 and August 2018, including all samples taken in the ENT field in children hospitalized in the ORL service of Med VI University Hospital of Marrakech.
Of the 115 samples, bacterial confirmation was found in 87% of cases. The average age was 45 years with a sex ratio M / F of 1 :4. 53% of the received samples were taken by swabbing, 14% were biopsies and 33% ear punctures, cellulite, atrial pus collection and drainage of nasal abcés. Le bacteriological profile was dominated by the bacteria Gram positive in 52% of cases. Isolates were represented mainly by Streptococcus (28%). Enterobacteriaceae accounted for 34% of isolates dominated by Klebsiella pneumoniae found in 20.5% of Pseudomonas case. The aeuroginosaà was found in 8% of cases. Haemophilus influenzae was isolated in 2%. The study isolates the antibiotic susceptibility of isolates showed sensitivity to penicillins 98% in isolates of Streptococcus pneumoniae. The Staphylococcus aureus strains were sensitive to methicillin. In enterobacteria, resistance to C3G was 18%. 1% of the isolates were of reduced susceptibility to carbapeneas and multidrug-resistant bacteria accounted for 9% in all the strains studied.
The procedure leading to the prescription of antibiotic therapy must be rigorous, systematic and justified.
